Question

我正在开发一个Android应用程序。应用程序中有两个活动。在操作栏中，我有一个按钮可以打开另一个活动。但是当我点击按钮时，默认的android动画发生在切换活动之间。我尝试使用intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);和overridePendingTransition(0, 0);，但无济于事。这种方法不起作用。我的应用程序的最小sdk是10。

我想要的是什么。

我希望单击按钮时不应该有动画。

我的代码

@Override
            public boolean onCreateOptionsMenu(Menu menu)
            {
                MenuInflater menuInflater = getMenuInflater();
                menuInflater.inflate(R.menu.main, menu);
                return true;
            }
            @Override
            public boolean onOptionsItemSelected(MenuItem item)
            {         
                switch (item.getItemId())
                {
                case R.id.action_button1:
                    Intent intent = new Intent(this, SecondActivity.class);
                    startActivity(intent);
                    finish();
                        overridePendingTransition(0, 0);
                        intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

            }
                return true;

        }

Answer 1

您正在调用finish()，然后尝试通过向intent添加标记来覆盖动画。在startActivity()中使用之前，必须先将标志添加到意图中。试试这个而不是你的代码：

Intent intent = new Intent(this, SecondActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
startActivity(intent);
overridePendingTransition(0,0); //0 for no animation
finish();

或者：

Intent intent = new Intent(this, SecondActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
overridePendingTransition(0,0); //0 for no animation

如果由于某种原因Inteng.FLAG_ACTIVITY_CLEAR_TOP或finish()不适合您，请尝试为android:noHistory=true中的<activity>设置Manifest.xml。请参阅here。

试试这个：）

"or p.sku like '%user_value%'"

的build.gradle：

protected static void start_Activity(Context context, Class<? extends Activity> activity) {
        if (context.getClass() == activity) { // current activity: do nothing
            return;
        }
        Intent intent = new Intent(context, activity);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);      
        ((Activity) context).finish();
        context.startActivity(intent);
        ((Activity) context).overridePendingTransition(0, 0);        
    }

Mainifest：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "vn.com.abuabi.animation"
        minSdkVersion 10
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
}

MainActivity：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="vn.com.abuabi.animation" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".SecondActivity"
            android:label="@string/title_activity_second" >
        </activity>
    </application>

</manifest>

SecondActivity：

package vn.com.abuabi.animation;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    public void doChange(View view) {
        Intent intent = new Intent(this, SecondActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);        
        finish();
        startActivity(intent);
        overridePendingTransition(0, 0);
    }
}

2个布局文件：

package vn.com.abuabi.animation;

import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;


public class SecondActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_second, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    public void doChange(View view) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        finish();
        startActivity(intent);
        overridePendingTransition(0, 0);
    }
}

如何在切换活动之间停止动画？
