Android Toast 总结(五种用法)
Toast大家都很熟，不多说。直接上图上代码。
具体代码如下：
main.xml:
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:orientation="vertical" android:padding="5dip" > <Button android:id="@+id/btnSimpleToast" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="默认" > </Button> <Button android:id="@+id/btnSimpleToastWithCustomPosition" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="自定义显示位置" > </Button> <Button android:id="@+id/btnSimpleToastWithImage" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="带图片" > </Button> <Button android:id="@+id/btnCustomToast" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="完全自定义" > </Button> <Button android:id="@+id/btnRunToastFromOtherThread" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="其他线程" > </Button></LinearLayout>
custom.xml:
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/llToast" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#ffffffff" android:orientation="vertical" > <TextView android:id="@+id/tvTitleToast" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="1dip" android:background="#bb000000" android:gravity="center" android:textColor="#ffffffff" /> <LinearLayout android:id="@+id/llToastContent" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="1dip" android:layout_marginLeft="1dip" android:layout_marginRight="1dip" android:background="#44000000" android:orientation="vertical" android:padding="15dip" > <ImageView android:id="@+id/tvImageToast" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> <TextView android:id="@+id/tvTextToast" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center" android:paddingLeft="10dip" android:paddingRight="10dip" android:textColor="#ff000000" /> </LinearLayout></LinearLayout>
package com.example.test;import android.app.Activity;import android.app.ActionBar;import android.app.Fragment;import android.content.Intent;import android.os.Bundle;import android.os.Handler;import android.view.Gravity;import android.view.LayoutInflater;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.widget.Button;import android.widget.EditText;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TextView;import android.widget.Toast;import android.os.Build;public class MainActivity extends Activity implements OnClickListener { Handler handler = new Handler(); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); findViewById(R.id.btnSimpleToast).setOnClickListener(this); findViewById(R.id.btnSimpleToastWithCustomPosition).setOnClickListener( this); findViewById(R.id.btnSimpleToastWithImage).setOnClickListener(this); findViewById(R.id.btnCustomToast).setOnClickListener(this); findViewById(R.id.btnRunToastFromOtherThread).setOnClickListener(this); } public void showToast() { handler.post(new Runnable() { @Override public void run() { Toast.makeText(getApplicationContext(), "我来自其他线程！", Toast.LENGTH_SHORT).show(); } }); } @Override public void onClick(View v) { Toast toast = null; switch (v.getId()) { case R.id.btnSimpleToast: Toast.makeText(getApplicationContext(), "默认Toast样式", Toast.LENGTH_SHORT).show(); break; case R.id.btnSimpleToastWithCustomPosition: toast = Toast.makeText(getApplicationContext(), "自定义位置Toast", Toast.LENGTH_LONG); toast.setGravity(Gravity.CENTER, 0, 0); toast.show(); break; case R.id.btnSimpleToastWithImage: toast = Toast.makeText(getApplicationContext(), "带图片的Toast", Toast.LENGTH_LONG); toast.setGravity(Gravity.CENTER, 0, 0); LinearLayout toastView = (LinearLayout) toast.getView(); ImageView imageCodeProject = new ImageView(getApplicationContext()); imageCodeProject.setImageResource(R.drawable.ic_launcher); toastView.addView(imageCodeProject, 0); toast.show(); break; case R.id.btnCustomToast: LayoutInflater inflater = getLayoutInflater(); View layout = inflater.inflate(R.layout.custom, (ViewGroup) findViewById(R.id.llToast)); ImageView image = (ImageView) layout .findViewById(R.id.tvImageToast); image.setImageResource(R.drawable.ic_launcher); TextView title = (TextView) layout.findViewById(R.id.tvTitleToast); title.setText("Attention"); TextView text = (TextView) layout.findViewById(R.id.tvTextToast); text.setText("完全自定义Toast"); toast = new Toast(getApplicationContext()); toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40); toast.setDuration(Toast.LENGTH_LONG); toast.setView(layout); toast.show(); break; case R.id.btnRunToastFromOtherThread: new Thread(new Runnable() { public void run() { showToast(); } }).start(); break; } }}
运行即可。
