Android commonly uses the following seven dialog boxes, which basically cover most of the application scenarios, so sometimes there is no need to define the dialog box by yourself unless the style of the dialog box does not meet the UI design. The commonly used seven dialog boxes are as follows:
- Simple dialog
- Simple list dialog
- Single-selection list dialog
- Multiple selection list dialog
- Progress bar dialog
- Edit dialog
- Custom dialog
1. Simple dialog
private void showNormalDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("简单对话框")
.setIcon(R.mipmap.ic_launcher)
.setMessage("这是一个简单对话框")
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//定义自己想要做的操作
showText("确定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}2. Simple List Dialog
private void showListDialog() {
final String[] items = new String[]{"上海", "北京", "湖南", "湖北", "海南"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("简单列表对话框");
//由于message 和 items 都属于弹出框的内容部分,两者只能显示一个, 所以千万不要加这句，不然列表显示不出来
// builder.setMessage("这是一个简单的列表对话框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText(items[which]);
}
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("确定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}3. Single-selection list dialog
private void showSingleChoiceDialog() {
final String[] items = new String[]{"上海", "北京", "湖南", "湖北", "海南"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("简单列表对话框");
//由于message 和 items 都属于弹出框的内容部分,两者只能显示一个, 所以千万不要加这句，不然列表显示不出来
// builder.setMessage("这是一个简单的列表对话框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setSingleChoiceItems(items, 1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText(items[which]);
}
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("确定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}4. Multiple selection dialog box.
private void showMultiChoiceDialog() {
final String[] items = new String[]{"上海", "北京", "湖南", "湖北", "海南"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("简单列表对话框");
//由于message 和 items 都属于弹出框的内容部分,两者只能显示一个, 所以千万不要加这句，不然列表显示不出来
// builder.setMessage("这是一个简单的列表对话框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setMultiChoiceItems(items, new boolean[]{false, false, false, false, false}, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
showText(items[which]);
}
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("确定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}5. The progress bar dialog box.
private void showProgressDialog() {
final ProgressDialog dialog = new ProgressDialog(this);
final int MAX_PROGRESS = 100;
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(false);
dialog.setIcon(R.mipmap.ic_launcher);
dialog.setTitle("提示");
dialog.setMessage("这是一个进度条对话框");
dialog.setProgress(0);
//监听取消时间
dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
showText("进度条结束");
}
});
dialog.show();
new Thread(new Runnable() {
@Override
public void run() {
int progress = 0;
while (progress < MAX_PROGRESS) {
try {
Thread.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}
progress++;
//非UI线程，可以处理DialogUI
dialog.setProgress(progress);
}
dialog.cancel();
}
}).start();
}6. The edit dialog is also a custom dialog.
private void showEditDialog() {
final EditText editText = new EditText(this);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.mipmap.ic_launcher);
builder.setTitle("编辑对话框");
builder.setMessage("这是一个编辑对话框");
builder.setView(editText);
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String input = editText.getText().toString();
showText(input);
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.create().show();
}7. Customize the dialog
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="299dip"
android:layout_height="match_parent"

</LinearLayout>
</LinearLayout>
</LinearLayout>
/**
* alertDialog提供了setView与setContentView两种方法自定义视图。
* setContentView是在AlertDialog的父类Dialog的方法，在父类Dialog方法中，是调用了Window.setContentView。这是对应整个对话框窗口的view。
* setView则是AlertDialog的方法,setView指的设置CustomView的部分而不是整个窗体,如果我们设置了buttonPanel又设置了contentPanel，则会在自定义的view下面显示自带的button。
