你的問題是不正確的,但我會回答它以兩種不同的方式
首先,如果你想添加的LinearLayout是在不同的XML文件,那麼你就可以充氣的XML文件,並把它添加到父的LinearLayout在你的Activity類這樣
Button testMessageButton = (Button) findViewById(R.id.TestMessageButton);
testMessageButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View view){
LinearLayout msgLayout = (LinearLayout) findViewById(R.id.MessageLayout);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
LayoutInflater vi = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = vi.inflate(R.layout.message_received, null);
v.setLayoutParams(params);
msgLayout.addView(v);
}
});
我已經更新了我的解決方案。問題的部分原因是在你的佈局文件
這是Activity類
import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
public class MainActivity extends AppCompatActivity {
private LinearLayout mainLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mainLayout = (LinearLayout)findViewById(R.id.main_layout);
Button addChatButton = (Button)findViewById(R.id.add_chat);
addChatButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
LayoutInflater vi = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout mView = (LinearLayout)vi.inflate(R.layout.test_layout, mainLayout, false);
mView.setLayoutParams(params);
mainLayout.addView(mView);
}
});
}
}
的Activity類的XML佈局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.inducesmile.mylinear.MainActivity">
<Button
android:id="@+id/add_chat"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="80dp"
android:text="@string/add_chat"
android:layout_gravity="center|center_horizontal"/>
</LinearLayout>
最後,包含的LinearLayout佈局文件是充氣並添加到根LinearLayout。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/ReceivedMessage"
android:background="@android:color/holo_blue_light"
android:visibility="visible">
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:src="@mipmap/ic_launcher"
android:id="@+id/ProfilePicture"
android:layout_weight="2" />
<TextView
android:text="@string/message"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="@+id/MessageText"
android:layout_weight="7"
android:paddingTop="14dp"
android:paddingBottom="14dp"
android:gravity="center_vertical" />
</LinearLayout>
你只想添加一個線性佈局到另一個線性佈局?那麼充氣機是什麼?爲什麼你用這個? –
因爲父LinearLayout是一個垂直的,並且只用於排序。水平LinearLayout是我想要插入的,它包含一個圖像和文本。我使用了充氣器,因爲您無法克隆LinearLayout。 – ashjack
