平時只是使用沒來得及總結，現在把7種常用的對話框手敲一邊

1、普通對話框

 private void showNormalDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("提示");
        builder.setMessage("是否退出");
        builder.setIcon(R.mipmap.ic_launcher);
        builder.setCancelable(false);
        builder.setPositiveButton("確認", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.setNeutralButton("忽略", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.create().show();
    }

2、等待對話框

 private void showWaitingDialog() {
        ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("提示");
        progressDialog.setMessage("進行中...");
        progressDialog.setIndeterminate(true);//模糊進度
        progressDialog.setCancelable(false);
        progressDialog.show();
    }

3、進度對話框

private void showProgressDialog() {
        final int MAX_PROGRESS = 100;
        final ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setProgress(0);
        progressDialog.setTitle("進度條");
        progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        progressDialog.setMax(MAX_PROGRESS);
        progressDialog.show();
        new Thread(new Runnable() {
            @Override
            public void run() {
                int progress = 0;
                while (progress < MAX_PROGRESS) {
                    try {
                        Thread.sleep(100);
                        progress++;
                        progressDialog.setProgress(progress);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                progressDialog.cancel();
            }
        }).start();

    }

4、列表選擇對話框

 private void showListDialog() {
        final String items[] = {"AA", "BB", "CC"};
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("列表對話框");
        builder.setIcon(R.mipmap.ic_launcher);
        builder.setCancelable(false);
        builder.setItems(items, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(AlertDialogActivity.this, items[which], Toast.LENGTH_SHORT).show();
            }
        });
        builder.create().show();
    }

5、單選對話框

  private void showSingleChoiceDialog() {
        final String items[] = {"AA", "BB", "CC"};
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("單選");
        builder.setCancelable(false);
        builder.setIcon(R.mipmap.ic_launcher);
        builder.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(AlertDialogActivity.this, items[which], Toast.LENGTH_SHORT).show();
            }
        });
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.create().show();
    }

6、多選對話框

 private void showMulChoiceDialog() {
        final String items[] = {"籃球", "足球", "排球"};
        final boolean selected[] = {true, false, true};
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("多選");
        builder.setCancelable(false);
        builder.setIcon(R.mipmap.ic_launcher);
        builder.setMultiChoiceItems(items, selected, new DialogInterface.OnMultiChoiceClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                Toast.makeText(AlertDialogActivity.this, items[which], Toast.LENGTH_SHORT).show();
            }
        });
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.create().show();
    }

7、自定義對話框

private void showMyDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("我的對話框");
        builder.setCancelable(false);
        builder.setIcon(R.mipmap.ic_launcher);
        View view = getLayoutInflater().inflate(R.layout.view_my_dialog, null);
        builder.setView(view);
        EditText et_name = view.findViewById(R.id.et_name);
        final String name = et_name.getText().toString().trim();
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(AlertDialogActivity.this, name, Toast.LENGTH_SHORT).show();
                dialog.dismiss();
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.create().show();
    }
