Dialog对话框有很多种，我这里主要讲了以下几种：
目录
普通对话框
button1=findViewById(R.id.dialog1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
AlertDialog dialog = new AlertDialog.Builder(DialogActivity.this)
.setIcon(R.drawable.tuimg)//设置标题的图片
.setTitle("我是对话框")//设置对话框的标题
.setMessage("我是对话框的内容")//设置对话框的内容
//设置对话框的按钮
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(DialogActivity.this, "点击了取消按钮", Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
})
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(DialogActivity.this, "点击了确定的按钮", Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
}).create();
dialog.show();
}
});样式：
列表对话框
button2=findViewById(R.id.dialog2);
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"};
AlertDialog dialog = new AlertDialog.Builder(DialogActivity.this)
.setIcon(R.drawable.tuimg)//设置标题的图片
.setTitle("列表对话框")//设置对话框的标题
.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(DialogActivity.this, items[which], Toast.LENGTH_SHORT).show();
}
})
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}).create();
dialog.show();
}
});样式：
单选列表对话框
button3=findViewById(R.id.dialog3);
button3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"};
AlertDialog dialog = new AlertDialog.Builder(DialogActivity.this)
.setIcon(R.drawable.tuimg)//设置标题的图片
.setTitle("单选列表对话框")//设置对话框的标题
.setSingleChoiceItems(items, 1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(DialogActivity.this, items[which], Toast.LENGTH_SHORT).show();
}
})
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}).create();
dialog.show();
}
});样式：
多选列表对话框
button4=findViewById(R.id.dialog4);
button4.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"};
final boolean checkedItems[] = {true, true, true, true};
AlertDialog dialog = new AlertDialog.Builder(DialogActivity.this)
.setIcon(R.drawable.tuimg)//设置标题的图片
.setTitle("多选对话框")//设置对话框的标题
.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
checkedItems[which] = isChecked;
}
})
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
for (int i = 0; i < checkedItems.length; i++) {
if (checkedItems[i]) {
Toast.makeText(DialogActivity.this, "选中了" + i, Toast.LENGTH_SHORT).show();
}
}
dialog.dismiss();
}
}).create();
dialog.show();
}
});样式：
半自定义对话框
在这里面还定义了一个view
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="@+id/dialog_edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>通过下面的语句调用：
View view = getLayoutInflater().inflate(R.layout.half_dialog_view, null); final EditText editText = (EditText) view.findViewById(R.id.dialog_edit);
button5=findViewById(R.id.dialog5);
button5.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//调用其他的xml文件
View view = getLayoutInflater().inflate(R.layout.half_dialog_view, null);
final EditText editText = (EditText) view.findViewById(R.id.dialog_edit);
AlertDialog dialog = new AlertDialog.Builder(DialogActivity.this)
.setIcon(R.drawable.tuimg)//设置标题的图片
.setTitle("半自定义对话框")//设置对话框的标题
.setView(view)
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String content = editText.getText().toString();
Toast.makeText(DialogActivity.this, content, Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
}).create();
dialog.show();
}
});样式：
